Rock Crusher

The Rock Crusher is a mid-game refining building that loosens nuggets from raw ore and can process many different resources. It is a starting-asteroid building on Folia Asteroid and is used to convert raw materials into useful secondary products, most notably Sand for Water Sieves and refined metal from raw metal.

It consumes 240 W of power. If supplied with standard power, it must be operated by a Duplicant; if supplied with Crushed Power, it works automatically and prefers that form of power. Each operating cycle takes 40 seconds, though the Duplicant’s Machinery attribute can shorten this. One Rock Crusher processes 100 kg per cycle, generally splitting the input into 50 kg of Sand and 50 kg of the corresponding refined metal for raw metal inputs. At full throughput, that is 1.25 kg/s of input and output, and a permanently supplied Rock Crusher can support about 2.5 Water Sieves with Sand.

• Raw metal is refined into the matching metal while producing Sand as a byproduct.
• Raw minerals are completely crushed into Sand, while Egg Shells are converted into Lime.
• Fossil is handled differently from other mineral inputs.
• A Steam Turbine can provide enough Crushed Power for two Rock Crushers at maximum output, since one turbine can supply up to 480 W of Crushed Power.

The delivery, Duplicant interaction, and output drop-off all occur at the second tile from the bottom left, which can make the operating animation misleading when placing or routing the building.
